MPQ20051
Low Noise, High PSRR, 1A
Linear Regulator
AEC-Q100 Qualified
The Future of Analog IC Technology
DESCRIPTION
The MPQ20051 is a low-dropout linear regulator
that supplies up to 1A current with a 140mV
dropout voltage. The externally-adjustable output
voltage has a range of 0.8V to 5V from an input
voltage of 2.5V to 5.5V.
An internal PMOS pass element allows for a low
130μA ground current, making the MPQ20051
suitable for battery-powered devices. Other
features include low-power shutdown, and short-
circuit and thermal protection.
The MPQ20051 is available in 3mm x 3mm 8-pin
QFN package.

QFN-8 (3mmx3mm) ................ 50 ...... 12 ... °C/W
Notes:
1) Exceeding these ratings may damage the device.
2) The maximum allowable power dissipation is a function of the
maximum junction temperature T
J
(MAX), the junction-to-
ambient thermal resistance
θ
JA
, and the ambient temperature
T
A
. The maximum allowable continuous power dissipation at
any ambient temperature is calculated by P
D
(MAX) = (T
J
(MAX)-T
A
)/θ
JA
. Exceeding the maximum allowable power
dissipation will cause excessive die temperature, and the
regulator will go into thermal shutdown. Internal thermal
shutdown circuitry protects the device from permanent
damage.
3) Devices
are
ESD
sensitive.
Handling
precaution
recommended.
4) The device is not guaranteed to function outside of its
operating conditions.
5) Measured on JESD51-7, 4-layer PCB.
